Variation in quality of care among older men with localized prostate cancer

Patient-reported outcomes before treatment for localized prostate cancer: are there differences among countries? Data from the True North Global Registry

INTRODUCTION

Similar Patient-Reported Outcomes (PROs) at diagnosis for localized prostate cancer among countries may indicate that different treatments are recommended to the same profile of patients, regardless the context characteristics (health systems, medical schools, culture, preferences…). The aim of this study was to assess such comparison.

METHODS

We analyzed the EPIC-26 results before the primary treatment of men diagnosed of localized prostate cancer from January 2017 onwards (revised data available up to September 2019), from a multicenter prospective international cohort including seven regions: Australia/New Zealand, Canada, Central Europe (Austria / Czech Republic / Germany), United Kingdom, Italy, Spain, and the United States. The EPIC-26 domain scores and pattern of three selected items were compared across regions (with Central Europe as reference). All comparisons were made stratifying by treatment: radical prostatectomy, external radiotherapy, brachytherapy, and active surveillance.

RESULTS

The sample included a total of 13,483 men with clinically localized or locally advanced prostate cancer. PROs showed different domain patterns before treatment across countries. The sexual domain was the most impaired, and the one with the highest dispersion within countries and with the greatest medians' differences across countries. The urinary incontinence domain, together with the bowel and hormonal domains, presented the highest scores (better outcomes) for all treatment groups, and homogeneity across regions.

CONCLUSIONS

Patients with localized or locally advanced prostate cancer undergoing radical prostatectomy, EBRT, brachytherapy, or active surveillance presented mainly negligible or small differences in the EPIC-26 domains before treatment across countries. The results on urinary incontinence or bowel domains, in which almost all patients presented the best possible score, may downplay the baseline data role for evaluating treatments' effects. However, the heterogeneity within countries and the magnitude of the differences found across countries in other domains, especially sexual, support the need of implementing the PRO measurement from diagnosis.

Association between hospital competition and quality of prostate cancer care

BACKGROUND

Hospitals account for approximately 6% of United States' gross domestic product. We examined the association between hospital competition and outcomes in elderly with localized prostate cancer (PCa). We also assessed if race moderated this association.

METHODS

Retrospective study using Surveillance, Epidemiology, and End Results (SEER) - Medicare database. Cohort included fee-for-service, African American and white men aged ≥ 66, diagnosed with localized PCa between 1998 and 2011 and their claims between 1997 and 2016. We used Hirschman-Herfindahl index (HHI) to measure of hospital competition. Outcomes were emergency room (ER) visits, hospitalizations, Medicare expenditure and mortality assessed in acute survivorship phase (two years post-PCa diagnosis), and long-term mortality. We used Generalized Linear Models for analyzing expenditure, Poisson models for ER visits and hospitalizations, and Cox models for mortality. We used propensity score to minimize bias.

RESULTS

Among 253,176 patients, percent change in incident rate of ER visit was 17% higher for one unit increase in HHI (IRR: 1.17, 95% CI: 1.15-1.19). Incident rate of ER was 24% higher for whites and 48% higher for African Americans. For one unit increase in HHI, hazard of short-term all-cause mortality was 7% higher for whites and 11% lower for African Americans. The hazard of long-term all-cause mortality was 10% higher for whites and 13% higher for African Americans.

CONCLUSIONS

Lower hospital competition was associated with impaired outcomes of localized PCa care. Magnitude of impairment was higher for African Americans, compared to whites. Future research will explore process through which competition affects outcomes and racial disparity.

Construction of nursing care quality evaluation indicators for post-anaesthesia care unit in China

AIMS AND OBJECTIVES

To establish a set of scientific and practical nursing care quality evaluation indicators for PACU in China.

BACKGROUND

No unified nursing care quality evaluation indicators for post-anaesthesia care unit (PACU) were found in China.

DESIGN

An international literature review, domestic cross-sectional survey and two-round e-Delphi study.

METHODS

The international literature review and domestic cross-sectional survey were conducted to identify the potential nursing care quality evaluation indicators for PACU. A total of 38 and 32 indicators were extracted from 24 articles and the cross-sectional survey respectively. Two rounds of e-Delphi study were conducted to collect opinions from a panel of 20 independent experts and establish the final version of the nursing care quality evaluation indicators for PACU. A GRRAS checklist was used to guide the reporting of this study.

RESULTS

Of 20 experts, 19 completed the first round of e-Delphi study and 18 completed the second round, with a response rate of 95% and 90% respectively. The experts' authority coefficient in the two rounds of e-Delphi study was 0.91 and 0.90 respectively. The Kendall W value of the two rounds ranged between 0.108 and 0.385 (p < .01). Four structure indicators, 12 process indicators and seven outcome indicators were included in the nursing care quality evaluation indicators for PACU.

CONCLUSIONS

With the methods of literature review, cross-sectional survey and e-Delphi study, we established a set of scientific and practical nursing care quality evaluation indicators for PACU, to improve the nursing care quality, reduce incidence of complications and ensure patient safety.

RELEVANT TO CLINICAL PRACTICE

The findings from this study enable nurses and managers in PACU settings to evaluate clinical nursing care quality using a robust framework.

Recognizing the emergency department’s role in oncologic care: a review of the literature on unplanned acute care

Background

The global prevalence of cancer is rapidly increasing and will increase the acute care needs of patients with cancer, including emergency department (ED) care. Patients with cancer present to the ED across the cancer care continuum from diagnosis through treatment, survivorship, and end-of-life. This article describes the characteristics and determinants of ED visits, as well as challenges in the effort to define preventable ED visits in this population.

Findings

The most recent population-based estimates suggest 4% of all ED visits are cancer-related and roughly two thirds of these ED visits result in hospitalization—a 4-fold higher ED hospitalization rate than the general population. Approximately 44% of cancer patients visit the ED within 1 year of diagnosis, and more often have repeat ED visits within a short time frame, though there is substantial variability across cancer types. Similar patterns of cancer-related ED use are observed internationally across a range of different national payment and health system settings. ED use for patients with cancer likely reflects a complex interaction of individual and contextual factors—including provider behavior, health system characteristics, and health policies—that warrants greater attention in the literature.

Conclusions

Given the amount and complexity of cancer care delivered in the emergency setting, future research is recommended to examine specific symptoms associated with cancer-related ED visits, the contextual determinants of ED use, and definitions of preventable ED use specific to patients with cancer.

Main reasons and predictive factors of cancer-related emergency department visits in a Hungarian tertiary care center

BACKGROUND

Identifying the reasons for the Emergency Department (ED) visit of patients with cancer would be essential for possibly decreasing the burden of ED use. The aim of our study was to analyze the distribution of the demographic and clinical parameters of patients with cancer based on the reasons for the ED visits and to identify possible predictive factors for their visits.

METHODS

This retrospective study, carried out at a large, public tertiary hospital in Hungary, involved all patients 18 years or over, who had received a cancer diagnosis latest within five years of their visit to the ED in 2018. Demographic and clinical characteristics were collected partly via automated data collection and partly through the manual chart review by a team of experts, including six emergency physicians and an oncologist. Five main reasons for the ED visit were hypothesized, pilot-tested, then identified, including those with cancer-related ED visits (whose visit was unambiguously related to their cancer illness) and those with non-cancer-related ED visits (whose visit to the ED was in no way associated with their cancer illness.) A descriptive approach was used for data analysis and binary logistic regression was used to determine predictive factors for patients with cancer visiting the ED.

RESULTS

23.2% of the altogether 2383 ED visits were directly cancer-related, and these patients had a significantly worse overall survival than patients with non-cancer related ED visits. Age 65 or below (Odds Ratio: 1.51), presence of two more comorbidities (OR: 7.14), dyspnea as chief complaint (OR: 1.52), respiratory cancer (OR: 3.37), any prior chemotherapy (OR: 1.8), any prior immune/biological treatment (OR: 2.21), any prior Best Supportive Care/palliative care (OR: 19.06), or any prior hospice care (OR: 9.43), and hospitalization (OR:2.88) were independent risk factors for the ED visit to be cancer-related.

CONCLUSIONS

Our study is the first to identify independent predictive factors of ED use by patients with cancer based on the chief cause of their visit in the Central and Eastern European region. These results may provide important information for the development of algorithms intended to identify the needs of care of patients with cancer at the ED.

Navigation programs relevant for African American men with prostate cancer: a scoping review protocol

BACKGROUND

The excess incidence and mortality due to prostate cancer that impacts African American men constitutes the largest of all cancer disparities. Patient navigation is a patient-centered healthcare system intervention to eliminate barriers to timely, high-quality care across the cancer continuum and improves health outcomes among vulnerable patients. However, little is known regarding the extent to which navigation programs include cultural humility to address prostate cancer disparities among African American men. We present a scoping review protocol of an in-depth examination of navigation programs in prostate cancer care-including navigation activities/procedures, training, and management-with a special focus on cultural context and humility for African American men to achieve health equity.

METHODS

We will conduct comprehensive searches of the literature in PubMed, Embase, Web of Science, and CINAHL Complete, using keywords and index terms (Mesh and Emtree) within the three main themes: prostate cancer, patient navigation, and African American men. We will also conduct a search of the gray literature, hand-searching, and reviewing references of included papers and conference abstracts. In a two-phase approach, two authors will independently screen titles and abstracts, and full-text based on inclusion/exclusion criteria. All study designs will be included that present detailed data about the elements of navigation programs, including intervention content, navigator training, and/or management. Data will be extracted from included studies, and review findings will be synthesized and summarized.

DISCUSSION

A scoping review focused on cultural humility in patient navigation within the context of eliminating disparities in PCa care among African American men does not yet exist. This review will synthesize existing evidence of patient navigation programs for African American prostate cancer patients and the inclusion of cultural humility. Results will inform the development and implementation of future programs to meet the unique needs of vulnerable prostate cancer patients in safety net settings.

Medical Utilization of Emergency Departments among Patients with Prostate Cancer: A Nationwide Population-Based Study in Taiwan

(1) Background: In Taiwan, prostate cancer is a major malignancy with an increasing incidence among men. This study explores the medical utilization of emergency departments among patients with prostate cancer in Taiwan. (2) Methods: This nationwide, population-based study was conducted via a cross-sectional method based on the Registry for Catastrophic Illness Patient Database from Taiwan’s National Health Insurance Research Database. Patients with newly diagnosed prostate cancer between 1997 and 2013 were enrolled in the study and divided into four treatment-related groups. The rate of emergency department presentation, disease categorization of emergency department visits, emergency department-related medical expenditures, and temporal trends were investigated. (3) Results: A total of 18,728 patients with prostate cancer were identified between 1997 and 2013, for whom 13,098 emergency department visits were recorded. The number of emergency department visits increased during the study period. The incidence rate for the medical utilization of emergency department visits was 822 per 1000 people during the study period. The incidence rates for patients with prostate cancer in the radical prostatectomy, radiotherapy, androgen deprivation therapy, and chemotherapy groups were 549, 1611, 1101, and 372, respectively. The average medical expenditure per emergency department visit was TWD 3779.8 ± 5116.2, and the expenditure was recorded for the chemotherapy group at TWD 4690.8 ± 7043.3. The most common disease diagnoses among patients with prostate cancer who presented to the emergency department were injury/poisoning (16.79%), genitourinary disorders (10.66%), and digestive disorders (10.48%). (4) Conclusions: This nationwide population-based study examined the emergency department visits of patients with prostate cancer in Taiwan, providing useful information for improving the quality of medical care.

Continuity of care in acute survivorship phase, and short and long-term outcomes in prostate cancer patients

Continuity of care is important for prostate cancer care due to multiple treatment options, and prolonged disease history. We examined the association between continuity of care and outcomes in Medicare beneficiaries with localized prostate cancer, and the moderating effect of race using Surveillance, Epidemiological, and End Results (SEER) - Medicare data between 2000 and 2016. Continuity of care was measured as visits dispersion (continuity of care index or COCI), and density (usual provider care index or UPCI) in acute survivorship phase. Outcomes were emergency room visits, hospitalizations, and cost during acute survivorship phase and mortality (all-cause and prostate cancer-specific) over follow-up phase. Higher continuity of care was associated with improved outcomes, and interaction between race and continuity of care was significant. Continuity of care during acute survivorship phase may lower the racial disparity in prostate cancer care. Future research can analyze the mechanism of the process.

Ethnographic investigation of patient-provider communication among African American men newly diagnosed with prostate cancer: a study protocol

INTRODUCTION

In the USA, African American men bear a disproportionate burden of prostate cancer (PCa) compared with all other groups, having a higher incidence and mortality, poorer quality of life and higher dissatisfaction with care. They are also less likely to receive guideline-concordant treatment (eg, undertreatment of aggressive disease). Inadequate patient-provider communication contributes to suboptimal care, which can be exacerbated by patients' limited health literacy, providers' lack of communication skills and time constraints in low-resource, safety net settings. This study is designed to examine the communication experiences of African American patients with PCa as they undertake treatment decision-making.

METHODS AND ANALYSIS

Using an ethnographic approach, we will follow 25 African American men newly diagnosed with PCa at two public hospitals, from diagnosis through treatment decision. Data sources include: (1) audio-recorded clinic observations during urology, radiation oncology, medical oncology and primary care visits, (2) field notes from clinic observations, (3) patient surveys after clinic visits, (4) two in-depth patient interviews, (5) a provider survey, and (6) in-depth interviews with providers. We will explore patients' understanding of their diagnoses and treatment options, sources of support in decision-making, patient-provider communication and treatment decision-making processes. Audio-recorded observations and interviews will be transcribed verbatim. An iterative process of coding and team discussions will be used to thematically analyse patients' experiences and providers' perspectives, and to refine codes and identify key themes. Descriptive statistics will summarise survey data.

ETHICS AND DISSEMINATION

To our knowledge, this is the first study to examine in-depth patient-provider communication among African American patients with PCa. For a population as marginalised as African American men, an ethnographic approach allows for explication of complex sociocultural and contextual influences on healthcare processes and outcomes. Study findings will inform the development of interventions and initiatives that promote patient-centred communication, shared decision-making and guideline-concordant care. This study was approved by the University of California San Francisco and the Alameda Health System Institutional Review Boards.

PROSPeCT: A Predictive Research Online System for Prostate Cancer Tasks

PURPOSE

An online clinical information system, called Predictive Research Online System Prostate Cancer Tasks (PROSPeCT), was developed to enable users to query the Alberta Prostate Cancer Registry database hosted by the Alberta Prostate Cancer Research Initiative. To deliver high-quality patient treatment, prostate cancer clinicians and researchers require a user-friendly system that offers an easy and efficient way to obtain relevant and accurate information about patients from a robust and expanding database.

METHODS

PROSPeCT was designed and implemented to make it easy for users to query the prostate cancer patient database by creating, saving, and reusing simple and complex definitions. We describe its intuitive nature by exemplifying the creation and use of a complex definition to identify a "high-risk" patient cohort.

RESULTS

PROSPeCT was made to minimize user error and to maximize efficiency without requiring the user to have programming skills. Thus, it provides tools that allow both novice and expert users to easily identify patient cohorts, manage individual patient care, perform Kaplan Meier estimates, plot aggregate PSA views, compute PSA-doubling time, and visualize results.

CONCLUSION

This report provides an overview of PROSPeCT, a system that helps clinicians to identify appropriate patient treatments and researchers to develop prostate cancer hypotheses, with the overarching goal of improving the quality of life of patients with prostate cancer. We have made available the code for the PROSPeCT implementation at https://github.com/max-uhlich/e-PROSPeCT .

Comparative analysis of long-term care quality for older adults in China and Western countries

Objective

Based on theoretical and methodological research and the results of a literature review, we evaluated and comparatively analyzed the quality of long-term care for older populations in China and in Western countries.

Methods

We performed a literature review, using the search terms long-term care and care services for older adults, in the databases ProQuest, CNKI, and Wanfang Data.

Results

Our comparative analysis demonstrated that the overall quantity of articles related to long-term care for older populations was relatively large. The literature comprises advanced accumulated experiences in terms of theoretical and methodological perspectives in developed countries. The field of long-term care is relatively young in China and we could retrieve only a few related studies.

Conclusions

The system of long-term care for older populations in China has much room for improvement. In addition, the evaluation criteria for long-term care quality remain controversial. Relevant research focusing on the quality of long-term care services in the country lacks comprehensive, systematic, and scientific validation, comparison, and evaluation. This topic warrants further evidence-based investigation in China.

The American Cancer Society 2035 challenge goal on cancer mortality reduction

A summary evaluation of the 2015 American Cancer Society (ACS) challenge goal showed that overall US mortality from all cancers combined declined 26% over the period from 1990 to 2015. Recent research suggests that US cancer mortality can still be lowered considerably by applying known interventions broadly and equitably. The ACS Board of Directors, therefore, commissioned ACS researchers to determine challenge goals for reductions in cancer mortality by 2035. A statistical model was used to estimate the average annual percent decline in overall cancer death rates among the US general population and among college-educated Americans during the most recent period. Then, the average annual percent decline in the overall cancer death rates of college graduates was applied to the death rates in the general population to project future rates in the United States beginning in 2020. If overall cancer death rates from 2020 through 2035 nationally decline at the pace of those of college graduates, then death rates in 2035 in the United States will drop by 38.3% from the 2015 level and by 54.4% from the 1990 level. On the basis of these results, the ACS 2035 challenge goal was set as a 40% reduction from the 2015 level. Achieving this goal could lead to approximately 1.3 million fewer cancer deaths than would have occurred from 2020 through 2035 and 122,500 fewer cancer deaths in 2035 alone. The results also show that reducing the prevalence of risk factors and achieving optimal adherence to evidence-based screening guidelines by 2025 could lead to a 33.5% reduction in the overall cancer death rate by 2035, attaining 85% of the challenge goal.

Prostate Cancer Disparities by Race and Ethnicity: From Nucleotide to Neighborhood

Prostate cancer (CaP) incidence, morbidity, and mortality rates vary substantially by race and ethnicity, with African American men experiencing among the highest CaP rates in the world. The causes of these disparities are multifactorial and complex, and likely involve differences in access to screening and treatment, exposure to CaP risk factors, variation in genomic susceptibility, and other biological factors. To date, the proportion of CaP that can be explained by environmental exposures is small and differences in the role factors play by race or ethnicity is poorly understood. In the absence of additional data, it is likely that environmental factors do not contribute greatly to CaP disparities. In contrast, CaP has one of the highest heritabilities of all major cancers and many CaP susceptibility genes have been identified. Some CaP loci, including the risk loci found at chromosome 8q24, have consistent effects in all racial/ethnic groups studied to date. However, replication of many susceptibility loci across race or ethnicity remains limited. It is likely that inequities in health care access strongly influences CaP disparities. CaP is a disease with a complex multifactorial etiology, and therefore any approach attempting to address racial/ethnic disparities in CaP must consider the many sources that influence risk, outcomes, and disparities.

An assessment of progress in cancer control

This article summarizes cancer mortality trends and disparities based on data from the National Center for Health Statistics. It is the first in a series of articles that will describe the American Cancer Society's vision for how cancer prevention, early detection, and treatment can be transformed to lower the cancer burden in the United States, and sets the stage for a national cancer control plan, or blueprint, for the American Cancer Society goals for reducing cancer mortality by the year 2035. Although steady progress in reducing cancer mortality has been made over the past few decades, it is clear that much more could, and should, be done to save lives through the comprehensive application of currently available evidence-based public health and clinical interventions to all segments of the population.

Cohort profile: the TrueNTH Global Registry - an international registry to monitor and improve localised prostate cancer health outcomes

PURPOSE

Globally, prostate cancer treatment and outcomes for men vary according to where they live, their race and the care they receive. The TrueNTH Global Registry project was established as an international registry monitoring care provided to men with localised prostate cancer (CaP).

PARTICIPANTS

Sites with existing CaP databases in Movember fundraising countries were invited to participate in the international registry. In total, 25 Local Data Centres (LDCs) representing 113 participating sites across 13 countries have nominated to contribute to the project. It will collect a dataset based on the International Consortium for Health Outcome Measures (ICHOM) standardised dataset for localised CaP.

FINDINGS TO DATE

A governance strategy has been developed to oversee registry operation, including transmission of reversibly anonymised data. LDCs are represented on the Project Steering Committee, reporting to an Executive Committee. A Project Coordination Centre and Data Coordination Centre (DCC) have been established. A project was undertaken to compare existing datasets, understand capacity at project commencement (baseline) to collect the ICHOM dataset and assist in determining the final data dictionary. 21/25 LDCs provided data dictionaries for review. Some ICHOM data fields were well collected (diagnosis, treatment start dates) and others poorly collected (complications, comorbidities). 17/94 (18%) ICHOM data fields were relegated to non-mandatory fields due to poor capture by most existing registries. Participating sites will transmit data through a web interface biannually to the DCC.

FUTURE PLANS

Recruitment to the TrueNTH Global Registry-PCOR project will commence in late 2017 with sites progressively contributing reversibly anonymised data following ethical review in local regions. Researchers will have capacity to source deidentified data after the establishment phase. Quality indicators are to be established through a modified Delphi approach in later 2017, and it is anticipated that reports on performance against quality indicators will be provided to LDCs.

A Systematic Review of Emergency Department Use Among Cancer Patients

BACKGROUND

Recent reports call for reductions in costly and potentially avoidable services such as emergency department (ED) visits. Providing high-quality and safe care for oncology patients remains challenging for ED providers given the diversity of patients seeking care and the unpredictable clinical environment. While ED use by oncology patients is appropriate for acute health concerns, some ED visits may be preventable with well-coordinated care and adequate symptom management.

OBJECTIVE

The aim of this study was to summarize available evidence regarding the incidence, predictors of, and reasons for ED visits among oncology patients.

METHODS

Keyword/MeSH term searches were conducted using 4 online databases. Inclusion criteria were publication date between April 1, 2003, and December 5, 2014; sample size of 50 or more; and report of the incidence or predictors of ED use among oncology patients.

RESULTS

The 15 studies that met criteria varied in study aim, design, and time frames for calculating ED utilization rates. The incidence of ED visits among oncology patients ranged from 1% to 83%. The 30-day standardized visit rate incidence ranged from 1% to 12%. Collectively, the studies lack population-based estimates for all cancers combined.

CONCLUSIONS

The studies included in this review suggest that rates of ED use among cancer patients exceed those of the general population. However, the extent of ED use by oncology patients and the reasons for ED visits remain understudied.

IMPLICATIONS FOR PRACTICE

Nurses are involved in the treatment of cancer, patient education, and symptom management. Nurses are well positioned to develop patient-centered treatment and care coordination plans to improve quality of care and reduce ED visits.

Cancer statistics for African Americans, 2016: Progress and opportunities in reducing racial disparities

In this article, the American Cancer Society provides the estimated number of new cancer cases and deaths for blacks in the United States and the most recent data on cancer incidence, mortality, survival, screening, and risk factors for cancer. Incidence data are from the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries, and mortality data are from the National Center for Health Statistics. Approximately 189,910 new cases of cancer and 69,410 cancer deaths will occur among blacks in 2016. Although blacks continue to have higher cancer death rates than whites, the disparity has narrowed for all cancers combined in men and women and for lung and prostate cancers in men. In contrast, the racial gap in death rates has widened for breast cancer in women and remained level for colorectal cancer in men. The reduction in overall cancer death rates since the early 1990s translates to the avoidance of more than 300,000 deaths among blacks. In men, incidence rates from 2003 to 2012 decreased for all cancers combined (by 2.0% per year) as well as for the top 3 cancer sites (prostate, lung, and colorectal). In women, overall rates during the corresponding time period remained unchanged, reflecting increasing trends in breast cancer combined with decreasing trends in lung and colorectal cancer rates. Five-year relative survival is lower for blacks than whites for most cancers at each stage of diagnosis. The extent to which these disparities reflect unequal access to health care versus other factors remains an active area of research. Progress in reducing cancer death rates could be accelerated by ensuring equitable access to prevention, early detection, and high-quality treatment.

Racial Differences in the Surgical Care of Medicare Beneficiaries With Localized Prostate Cancer

IMPORTANCE

There is extensive evidence suggesting that black men with localized prostate cancer (PCa) have worse cancer-specific mortality compared with their non-Hispanic white counterparts.

OBJECTIVE

To evaluate racial disparities in the use, quality of care, and outcomes of radical prostatectomy (RP) in elderly men (≥ 65 years) with nonmetastatic PCa.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective analysis of outcomes stratified according to race (black vs non-Hispanic white) included 2020 elderly black patients (7.6%) and 24,462 elderly non-Hispanic white patients (92.4%) with localized PCa who underwent RP within the first year of PCa diagnosis in the Surveillance, Epidemiology, and End Results (SEER)-Medicare database between 1992 and 2009. The study was performed in 2014.

MAIN OUTCOMES AND MEASURES

Process of care (ie, time to treatment, lymph node dissection), as well as outcome measures (ie, complications, emergency department visits, readmissions, PCa-specific and all-cause mortality, costs) were evaluated using Cox proportional hazards regression. Multivariable conditional logistic regression and quantile regression were used to study the association of racial disparities with process of care and outcome measures.

RESULTS

The proportion of black patients with localized prostate cancer who underwent RP within 90 days was 59.4% vs 69.5% of non-Hispanic white patients (P <  001). In quantile regression of the top 50% of patients, blacks had a 7-day treatment delay compared with non-Hispanic whites. (P <  001). Black patients were less likely to undergo lymph node dissection (odds ratio [OR], 0.76 [95% CI, 0.66-0.80]; P < .001) but had higher odds of postoperative visits to the emergency department (within 30 days: OR, 1.48 [95% CI, 1.18-1.86]); after 30 days or more (OR, 1.45 [95% CI, 1.19-1.76]) and readmissions (within 30 days: OR, 1.28 [95% CI, 1.02-1.61]); ≥ 30 days (OR, 1.27 [95% CI, 1.07-1.51]) compared with non-Hispanic whites. The surgical treatment of black patients was associated with a higher incremental annual cost (the top 50% of blacks spent $1185.50 (95% CI , $804.85-1 $1566.10; P < .001) more than the top 50% of non-Hispanic whites). There was no difference in PCa-specific mortality (P = .16) or all-cause mortality (P = .64) between black and non-Hispanic white men.

CONCLUSIONS AND RELEVANCE

Blacks treated with RP for localized PCa are more likely to experience adverse events and incur higher costs compared with non-Hispanic white men; however, this does not translate into a difference in PCa-specific or all-cause mortality.

Prostate Cancer Registries: Current Status and Future Directions

CONTEXT

Disease-specific registries that enroll a considerable number of patients play a major role in prostate cancer (PCa) research.

OBJECTIVE

To evaluate available registries, describe their strengths and limitations, and discuss the potential future role of PCa registries in outcomes research.

EVIDENCE ACQUISITION

We performed a literature review of the Medline, Embase, and Web of Science databases. The search strategy included the terms prostate cancer, outcomes, statistical approaches, population-based cohorts, registries of outcomes, and epidemiological studies, alone or in combination. We limited our search to studies published between January 2005 and January 2015.

EVIDENCE SYNTHESIS

Several population-based and prospective disease-specific registries are currently available for prostate cancer. Studies performed using these data sources provide important information on incidence and mortality, disease characteristics at presentation, risk factors, trends in utilization of health care services, disparities in access to treatment, quality of care, long-term oncologic and health-related quality of life outcomes, and costs associated with management of the disease. Although data from these registries have some limitations, statistical methods are available that can address certain biases and increase the internal and external validity of such analyses. In the future, improvements in data quality, collection of tissue samples, and the availability of data feedback to health care providers will increase the relevance of studies built on population-based and disease-specific registries.

CONCLUSIONS

The strengths and limitations of PCa registries should be carefully considered when planning studies using these databases. Although randomized controlled trials still provide the highest level of evidence, large registries play an important and growing role in advancing PCa research and care.

PATIENT SUMMARY

Several population-based and prospective disease-specific registries for prostate cancer are currently available. Analyses of data from these registries yield information that is clinically relevant for the management of patients with prostate cancer.

Racial and ethnic differences in time to treatment for patients with localized prostate cancer

OBJECTIVE

To investigate the racial/ethnic differences in the time to treatment among patients with prostate cancer.

MATERIALS AND METHODS

All 3448 men diagnosed with localized prostate cancer at Kaiser Permanente Southern California from 2006 to 2007 were identified. The patients were passively followed up through their electronic health records until definitive treatment, defined as the first treatment given with curative intent within 1 year of diagnosis. Cox proportional hazard models, with PROC SURVEYPHREG procedures, were used to account for the variability in time to the different treatments within multiple medical centers.

RESULTS

The overall median time to treatment was 102 days, with modest differences for whites (100 days), blacks (104 days), and Hispanics (99 days). In the adjusted model, black men had a significantly longer time to surgery (adjusted hazard ratio 0.74, 95% confidence interval 0.56-0.91) compared with white men. Hispanic men (adjusted hazard ratio 1.44, 95% confidence interval 1.07-1.74) experienced significantly shorter times to radiotherapy compared with white men. No difference was found in the time to radiotherapy or brachytherapy for black men relative to white men.

CONCLUSION

These data suggest that minimal racial/ethnic differences exist in the time to treatment after the diagnosis of prostate cancer in this equal-access setting. This is encouraging, but does not mean that all men were satisfied with their treatment choice.

Racial/Ethnic patterns in prostate cancer outcomes in an active surveillance cohort

Introduction. Concern regarding overtreatment of prostate cancer (CaP) is leading to increased attention on active surveillance (AS). This study examined CaP survivors on AS and compared secondary treatment patterns and overall survival by race/ethnicity. Methods. The study population consisted of CaP patients self-classified as black or white followed on AS in the Center for Prostate Disease Research (CPDR) multicenter national database between 1989 and 2008. Secondary treatment included radical prostatectomy (RP), external beam radiation therapy or brachytherapy (EBRT-Br), and hormone therapy (HT). Secondary treatment patterns and overall survival were compared by race/ethnicity. Results. Among 886 eligible patients, 21% were black. Despite racial differences in risk characteristics and secondary treatment patterns, overall survival was comparable across race. RP following AS was associated with the longest overall survival. Conclusion. Racial disparity in overall survival was not observed in this military health care beneficiary cohort with an equal access to health care.

Health services research in urology

OBJECTIVES

Health services research (HSR) is increasingly important given the focus on patient-centered, cost-effective, high-quality health care. We examine how HSR affects contemporary evidence-based urologic practice and its role in shaping future urologic research and care.

METHODS

PubMed, urologic texts, and lay literature were reviewed for terms pertaining to HSR/outcomes research and urologic disease processes.

RESULTS

HSR is a broad discipline that focuses on access, cost, and outcomes of Health care. Its use has been applied to a myriad of urologic conditions to identify deficiencies in access, to evaluate cost-effectiveness of therapies, and to evaluate structural, process, and outcome quality measures.

CONCLUSIONS

HSR utilizes an evidence-based approach to identify the most effective ways to organize/manage, finance, and deliver high-quality urologic care and to tailor care optimized to individuals.
